To all whom it may concern c it known that I, PATRICK J. YOUNG, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Supports; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in riveting devices and particularly to devices for holding the heads or" the rivets at one side of the plates being secured while the other ends of the rivets are upset.

One object of the present invention is to provide a novel and improved device of this character which obviates the use of the different lengths of standard sections now employed. It often happens that the required length is either too long or too short for the sections on hand. In the latter case the standard or support must be jacked up to the required height. With the present device these standard sections are done away with, or the necessity of changing one for another, the standard being capable of easy and quick adjustment to a very fine degree.

The device is particularly adapted for use in riveting the plates on ships, and as the construction of ships is now a prime work, the saving of time and labor, with the consequent increase of the output of the shipyard, is of the greatest importance. Hence the value of the present device in the ship industry.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing;

Figure 1 is an elevation of the invention shown in connection with a portion of a ship, the ship being in section.

Fig. 2 is an enlarged vertical longitudinal sectional View through the device in a plane parallel to that of Fig. 1.

Fig. 3 is an enlarged horizontal sectional view taken 011 the line 33 of Fig. 1.

Fig. 4: is an enlarged fragmentary elevation of the members 13 and 17.

Referring particularly to the accompanying drawing, 10 represents a hollow standard which is screwed into the upper end of thednverted conical foot member-11, said foot member having a pointed toe 12 in the lower end thereof. A hollowed member 13 having an internal shoulder in the lower portion receives the upper end of the standard threadedly, as shown at 14-. The upper end of the member 13 is formed with a pair of diametrically opposite inturned lugs 15 which engage in the circular groove 16 formed in the lower end of the internally threaded sleeve 17. This sleeve is arranged to receive therein the externally threaded bolt 18, which bolt has its upper end reduced and externally threaded, as shown at 19. This portion 19 is engaged in the lower end of the cylinder 20 which has therewithin the rivet holding piston 21. The said piston is arranged to be elevated to push the rivet through the openings in the overlapped plates 22, by air which is let into the cylinder, below the piston, by means of the controlling valve 23.

Thus when the device is to be used, the foot is properly placed with its toe in a beam or other supported member, so that the upper end of the piston is directly beneath the head of the rivet. The rivet is placed in the plate openings with the usual tongs and in the usual manner. The operator 0% the present device then opens the air valve which forces the piston upwardly and drives the rivet into the openings of the plates. The riveter then operates the upsetter from the other side of the plates, while the man at the holding device holds the device so that the upper end of the piston is firmly engaged with the head of the rivet. Should the upper end of the piston not quite reach the head of the rivet, or not quite push it far enough, the operator simply turns the sleeve 17 which causes the bolt 18 to rise, and by properly manipulating this sleeve the piston can be brought into the proper relation with respect to the rivet head. Should the piston be too high the sleeve 17 can be turned downwardly, as will be readily understood.

Thus the ordinary standard sections of different lengths, which the workman must have to adjust the device to the proper relation to the rivet head, are done away with, and a simple and eifective device which will save time and labor produced.

What is claimed is:

1. A support for use in connection with a riveting machine comprising a standard having a foot, a cap engaged on the upper end of the standard, a sleeve having its lower end removably and rotatably engaged in the cap, and a rivet engaging member adjustably engaged in the sleeve.

2. A support for use in connection with a riveting machine comprising a standard having a foot, a cap engaged on the upper end of the standard, said cap having a pair of inwardly directed lugs, an internally threaded sleeve engaged with thecap and having a circumferential groove for the reception of the sald lugs, and an externally threaded stem engaged in the sleeve and provided with means for supporting engage- 15 ment with a rivet holder.

In testimony whereof, I affix my signature,

in. the presence of two witnesses.
